152 BOTANY. Astee* eeic^folius, Rothrock (in Botanical Gazette, Jan., 1877).— WiUow Spring, Arizona (208) ; Santa Fd, N. Mex. (14). Eeigekon Canadense, L.—Central Arizona (718, 764). Eeigeeon compositum, Pursh —Colorado (493) ; also var. discoideus. Gray, from Utah. Number 496 from Colorado is a form near E. pedatum, Nutt., but still somewhat hirsute, and the leaves and petioles distinctly hispidly cihate, and the involucre as hairy as the typical E. compositum. Eeigeeon geandifloeum. Hook., var. elatius. Gray (Enum. Pl Par¬ ry).—A foot or more high, with several heads; stems leafy almost to the summit; scales of the involucre with extremely delicate tips, and united into a woolly mass.—Mosquito Pass, Colorado (487, 490). Eeigeeon uesinum, D. C Eaton (in vol V, King's Survey, p. 148).— (495.) Eeigeeon unifloeum, L., var.—4-10' high, more or less pubescent, a single head terminating the erect, sparsely leaved stem; lower leaves spatu- late-oblong, tapering to a hispidly ciliate petiole; stem-leaves oblanceolate, sessile; scales of the involucre somewhat crowded, hairy, and usually with purple, tapering tips; rays about 60, purple, twice as long as the disk- flowers (achenia too young); pappus almost uniform and a little shorter * " Diplopappus ericoides, T. & 6.—To save labor to some others who, like myself, work under the double disadvantage of a rather limited library and an herbarium (rich enough in the later new species) with but few specimens from the original sets made prior to 1862,1 put the following in print. From our present standpoint it is evident that Diplopappus as formerly understood must be partitioned out among other neighboring genera, and of the species that concern us here, one goes to section Ericame¬ ria of Aplopappus, and the other to section Orthombris of Aster. In the unavoidable changing of names a confusion arises under the name above given, i. e., Diplopappus ericoides, there being two plants that bear the name in herbaria aud books. The following may in some sense clear up the matter: Diplopappus ericoides, T. & G. Bucephalus ericoi¬ des, Natt. "Inula? ericoides, Torr.I in Ann. Lye. New York, 2, p. 212. Chrysopsis ericoides, Eaton, Man. Bot." Now placed in Aster under Sect. Orthomeris. As the name ericoides is preoccupied in this genus I suggest for it Aster ericosfolius, which indicates eveu more closely its general habit. See also Diplopappus ericoides, T. & G., Vol. V., King's Eeport; Pl. Wright., p. 78; Pl. Fendl., p. 69; Bot. Mex. Bound., p. 78. The two plants are so different iu habit,—the one suggestive of (so far as arrangement of the foliage goes) Erica, and the other of Adenostoma fasciculatum, Hook, & Arn., or of Eriotjonvm fascicu- /a<«m, Benth.—as well as in habitat, that any further description is unnete8Bary."—Botanical Gazette, January, 1877. Diplopappus ericoides. Less. Aplopappus ericoides, DC, and apparently also of Hooker and Arnott. See DC, Prod. V., p. 278; Bot. Beechy, p. 146; .and Fl. Cal. L, p. 313. In the last, Ericameria microphylla, Nutt., is also cited as another name for the oame, and by this it appears in Flora of North America, T. & G., 2, p. 236.
